H EATING OIL-STOVE.

SPECIFICATION forming part of, Letters Patent No. 521,813, dated I une 26,1894. Application iiled February 27, 1893. Serial No.463-,843. (No model.)

To all whom it may concern:

Be it known, that I, VICTOR E. RANDALL, a citizen of the United States, anda resident of Burlington, in the county of Calhoun and State of Michigan, have invented a new and useful Heating Oil-Stove, of which the following is a correct description.

The invention relates to that class of stoves in which hydrocarbon or other oils adapted to the purpose are employed as fuel, the same being supplied from a reservoir to any desired or convenient number of wicks.

The invention consists incertain novel parts or co-operating assemblages of parts in an oil stove whereby the oil reservoir may be constructed with less material and labor; whereby the burner tube and oil reservoir may be maintained at a veryrlow temperature; whereby the substructure or base of the stove can be cheaply made and easily placed together; whereby the combustion chamber and drum vportion will radiate a great amount of heat, and whereby, exterior air may enter between the combustion chamber and drum section and together with the products of combustion bedischarged from the top ofthe stove.

In the accompanying drawings, which constitute a part of this specification: Figure l represents atransverse vertical section of my improved stove, the arrows indicating air passage ways. Fig. 2 is aplan of the lower base section, with the oil reservoir and burner intact. Fig. 3 is a plan of the complete substructure or base section. Fig. 4 is a plan of the lower drum section, on the line fr, of

Fig. l. Fig. 5 is a vertical and part section of the wick or burner tube in detail. Fig. 6 is a plan oi' the combustion chamber on the line z, z, Fig. 1.

In the drawingslike letters of reference refer to'corresponding parts in the views.

The base a, of the stoveA A, consists of a rectangular downwardly and outwardly flaring air receiving section which is supported upon legs a', ct, a', &c. The base top a2, together with the upper portion of the base vbottom a, forms the oil reservoir section, the

reservoirs B, B, resting upon the downwardly and inwardly curved brackets or lugs a, a4, dac.,k of the lower base section. The reservoir section embraces the upper portion of the rectangular base a, the rectangular base top n.2,vthe outer or secondary rectangularair passage d5, the cylindrical and parallel twin or double reservoirs B, B, the primary or in'- ner air passages b, an, annular wick tube or burner C, and the annular and inner draft portion c', of the burner C, formed by the interior wall of said burner.

vThe cylindrical oil reservoirs B, B, are .received upon the curved and downwardly indrawn lugs a4, a4, dac., of the lower or base section a; the cylindrical oil reservoirs B, B, are spaced therefrom and lie parallel with respect to each other; an annular burner C, or burners, being centrally located therein between; an oil conduit c2, uniting the oil reservoirsand engaging at the side of the burner C,-whereby the latter may be supplied with oil; cross stays or braces b', b', together with the burner C, irmly soldered to said reservoirs, tend to make the said assemblages of parts intact and very rigid.

The rectangular and upwardly indrawn base top section 0,2, is, in its lower portion, fitted with a rabbet or interior seat a, which overlaps a corresponding upper section of the substructure or base bottom a.

The reservoir section B, B, and the burner C, having been suitably placed upon the lugs a4, c4, of the base section a, the upper base section a2, is then placed thereon; tightening bolts 01,07., (Fig. 3) are received through the top section a2, and pass through the lugs d', d', (Fig. 2) of the lower base section a, of the stove; -as the tightening boltsd, d, are drawn together the lugs a7, a7, dro., of the upper base sect-ion are caused to impinge the oil reservoirs B, B, and ,tlrmly secure the parts a, a2, and B, B, firmly together. v

b2, is an oil inlet to the reservoirs B, B, an b3, is a tube entering one of the oil reservoirs opposite to the oil filling aperture; the said tube b3, contains a float b4, .which not only indicates the presence and absence ofoil in the said reservoirs, but also forms a vent by which the air may enterthe said oil reservoir and allow forthe free combustion toY the burner or burners, and it valso allows the oil to seek its level in the oil reservoir with the one from which oil enters in the manner 'of replenishing.Y Y.

The base top section a2, has holes or aper- IOO tures d3, through which the oil lilling tube b2, and the oil indicating iloat h4, may protrude for the easy and quick facilitating,or operation of the stove.

The annular combustion chamber or section D, commencing at a point near its lower end and extending upwardly is fluted, the portions s, s, tbc., being vertical and the mica or window sections s', s', &C.,trend inwardly at a point from near the bottom thereof. The bottom of said combustion chamber being bowl shaped and adapted to iit over a raised 0r neck portion s2, of the base top section a2, of the stove. Within the bottom of the combustion chamber or section D, is an annular open and upwardly indrawn air defiector s3, which forms with the neck portion 32, of the base top section a2, an annular air passage around the upper end of the burner C. Surmounting the combustion section D, is the casing ordrum section E. Upon the neck or upwardly indrawn portion of the top base section a2, are suitably provided ears 7.a, 7c, which coincide and operate with similar portions on the bowl shaped portion of the combustion section D, and connectively pivoted therewith, forming a hinge by which the said combustion section may be tilted as occasion may desire in the operation of snuiiing the wick, the.

Within the central or draft section c', of the burner C, is a vertical post n, secured to the burner by the arms or wings n', fn', &c., this post extends above the burner one and tive sixteenths of an inch and is surmounted by the horizontal iiame spreading section n2, whose periphery is coincident with the inner walls of the burner C, at points near the periphery of said iiame spreading section and protruding from the lower surface thereof are lugs n3, n3, dsc., which are located about five-sixteenths of an inch within the circle of the wall of the burner C. A collar or air distributing band c6, is received upon the lugs 713,123, tbc., of the flame spreading section n2, and its upper edge is burred or turned outward and extends above the burner tube proper about eleven sixteenths of an inch.

A collar H, forms a union with the drum E, and the upper extremity of the combustion section D. The collar H, is annular and the outer portion forms an ornamental band, while connected therewith and forming a portion thereof is a widened inner and cylindreconical portion h, its lower portion being received by the indrawn or mica sections s', of the combustion section D, while its upper or top portion extends up within the drum section E, and is surmounted by the inverted cone section G supported therefrom by the legs g, g, duc. The exterior or ornamental portion and the inner and cylindroconical portion h, of the collar H, are united with the horizontal web sections h', h', ae., and are cast with and form a part of the said collar. Between the web or horizontal sections 7L', 71,', &c., of the collar H, are apertures i', t', dac., the

apertures fifi, aforesaid being aligned with the indrawn or mica sections s', s', dsc., of the combustion section D. The web or horizontal section h', 7L', dac., of the collar Il, are fitted upon and cover the vertical or ribbed section s, s, dac., of the combustion section D. Snrmounting the drum section E, are the usual top collar and discharge dome F, of the usual construction and 7a', is the usual rack and pinion operating wick spindle for regulating the fiame.

The operating of the stove to persons skilled in the art will bein the main apparent from the foregoing description of its construction. The oil reservoir having been duly filled and the wick having been lighted, air will be supplied to the fiame internally through the central draft passage c', of the burner, distributing it between the walls of the collar c6, and the inner burner tube and between the iiame spreading section n2, and the collar c6; exteriorly the air passes upward and around the burner between the indrawn or neck portions s, of the base top section a2, which opens into the space above the burner and within the defiectin g collar s3, therewith uniting with the air currents from the interiorof the burner and together are discharged into the coinbustion section D. The air currents which are received by the combustion section D, and the secondary air inlets t', fi, dre., are in termingled as they approach the exit formed between the radiating or drum section E, and the inverted cone-section G. It will be evident that as the exterior air currents pass upward and over the highly heated surfaces of the mica sections s', s', &c., and unite with the products of combustion from the combustion section D, between the highly heated surfaces of the cone section G, and the radiating or drum section E, unt-il discharged from the top of the stove are subjected to extreme caloriiic.
